This study evaluated the relationship between meeting the Nutrition Recommendations and mortality from all causes in a cohort of 1,623 men from the Quebec City area followed from 1985 to 1991. The usual dietary intake was assessed by a self-administered semi-quantitative food frequency questionnaire. Most participants did not meet the Nutrition Recommendations. During the follow-up 69 men died. The mortality was significantly lower among those who did not meet the recommendations for total fat (RR = 0.45, CI: 0.25-0.81) or for carbohydrates (RR = 0.49, CI: 0.26-0.92). This unexpected result could be attributable to an excessive alcohol intake or to dietary changes in the direction of the Nutrition Recommendations, made prior to the dietary assessment often because of illness. It would be interesting to continue the follow-up of this cohort to evaluate the long-term effect of a diet meeting the Nutrition Recommendations on mortality from all causes.
In order to pursue a study on the growth and development of French-Canadian children from birth to 6 years of age, 496 pregnant women were selected in the Montreal area. A complete survey of the family's social and medical background, along with the parents' height and weight was recorded through a prenatal interview that generally took place towards the last trimester of pregnancy. In the course of the same interview the mother participated in a quantitative investigation of her own diet during pregnancy, and filled in a 24-hour food record that was revised by the nutritionist to further precise the actual quantities of food ingested. Perinatal events and anthropometric measurements at birth were recorded. The babies were examined at the Center every 3 months up to the age of 18 months, and then at 24 months old; thereafter they are seen annually within more or less 7 days of the date of their birthday. The medical examinations are performed by a multi-professional team responsible for analyzing the various factors influencing the growth and development of the child. Since nutrition is one of the outstanding aspects of this study, the present article deals with the investigation of two known methods for evaluating the mother's nutrition during pregnancy, as well as that of the child during his first years of life.
